(a)

balanced reaction :

FeCl3â€¢7H2O + 3 HCO3-Â Â Â Â Â Â --------------------------> Fe(OH)3(s) + CO2 + 3 Cl- + 7H2O

288.3 gÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 106.87 g

20 x 10^-3 gÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ?

Fe(OH)3 mass = 20 x 10^-3 x 106.87 / 288.3

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 7.41 x 10^-3 g

Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â = 7.41 mg /L

ferric hydorxide = 7.41 mg /L
